" Whether used inc'onnection With one'or both This invention relates tola fastening device adapted to 'be operatively applied ,in

connectionv with a sash, movable panel or other analogous movable memberto Which the devicelmay be applicable. Y,

The primary object of the invention is to hold a Window sash, panel oranalogous mov-y able member either locked in closed position or inpartiallyopen position, and to have y'theimproved fastener of suchconstruction thatl it may Vbe readily reversed 'to engage oppositeportions of a sashfor Window frame, panel or other ,movable ymember tohold the .same against movement. y

A further object ofthe'invention is to lprovide Aa fastener-. of' theclass specified, which is 'simple in construction and economical'`in'manufacture, the improved device,

sides of' a sash or Window frame, panel or other movable umember, being,the same in construction, orwhere 'tivo of the improved devices areused, they will be duplicates.

i A" furtherl object fofthednvention is to` provide a fastening deviceofthe class speci-y fied Which lmay also serve to eliminate' allvibratory noises or rattling of the Window sash, panel` or othermovablemember, and also'to effect a tight joint, particularly of aWindow sash With'respect tothe inner and outer stops of a Window frame,to'ezgclude cold air andthereby renderthe 'use of Weather stripsfand`lili@ air-eXcluding means.

unnecessary.

A stillfurther object' of the invention is to provide a fastening deviceof the class specified, Which'may be readily appliedfin operativeposition Without requiring' any- `special mechanical knowledge, andmore.-

over, toprovide a'fastening device which is*` `ofthe devices in full anddotted lines vto il-i lustrate the operationof the same.

Fig. 7 is an elevation of a slightly modi;

fied form of the fastening device;

Fig. 3 is a vieW similar to Fig. 2, showing one, 'of the improvedfastening devices in "locking position to prevent `raising of the vc5 yYThe improved fastening deviceis shown applied to aivindow sash, a pairof the devices being illustrated as fastened to the side member. of thesash in Fig. 1but it Will be understood that the said fastening deviceWilloperate with equal efficiency if ap-f` plied to the inner oppositeside portions "of the frame and bindagainst the adjacent-side members ofthe sash. Furthermore, it mayVv at'times be desirable lto. use only` oneof the` V improved devices, and it is 'obvious that the:y invention willnot be in the least modified by either a single or double use oftheilnproved f device. Y

Structurally, the improved device comprises a flat body member 5, Vofsuitable thickness, having the opposite ends 6 and 7 struck 0r bent upat right angles tothe body member in the'form of flanges. These endVflanges are curved in the arcs of. circles struck from the centers A andB inthe preferred form of `.thef device, Vand from the centers C and Din the modified formk shown by Fig.` 7. In the preferred form ofthefastening devicel as shown by Figs. l to 6, inclusive, the opposite sideedges are of'duplicate contour, there being .tWo parallel straight sideedge portions intersected at their inner terminals by obtusely-arranged,shorter straight side edge portions 9,- which continue outwardlyi'to thecurved outer. surfaces of the flanges 6 and 7, these` curved flangeswith the body 5l essentially forming a double'cam for reversibleoperation. The flanges 6 and` 7 are equidistant from the Vcenter of thelbody 5, and the generall construction of Vthe improved device is suchthat one standardized form of the same may ln applying the improveddevice, it will Y be impossible to place the Vsame in a wrong positionon fthe side members of the window sash oi' inner opposite sides of thewindow frame or panel casing, `for the reason that when the device isplaced on the casing, it is only necessary to` dispose any one of thestraight edges 8 or 9 parallel with the edge of the casing or sash orpanel casing, as the case may be, with any point touching the edge ofthe window frame, sash or casing, and if this mode of application isproperly followed, the device will be inproper position for operation.lVhen placed on the right side of the inner portion of the Vwindow frameor side member `of the sash, the device operates as a positive stopftoprevent the sash from being lowered, and when thel device is placed A ontlie le'i't side of the window frame or sash as shown byFig. 1, itoperates to hold the window against raising movement, and

bythis means asafety device is provided and also all vibration andrattling noise Vwill be positively eliminated. When the device appliedto both the right and left- :15 hand sidesof awindow frame or sash inprop-er operative position, a slight pressure thereon, either downwardlyor upwardly as `ithe'casc may be, will immovably hold the sash or panelin place. When the window sash is 40 closed, as in cold or windyweather,thel iin` proved device is operated on both sidesto set up a binding`act-ion relatively to the window sash and Vseal the window or tightly'hold the same in such manner as to obstruct Vall ingress of cold air4and dust, and by this means the use of weather stripping is obviated.Vhen the window is closed and has the improved device applied toopposite sides thereof as shown in Fig. l, a sealing of the window sashto obstruct ingress of cold air and dust may be effectively obtained by.first pressing outwardly on the sash and then operating the device tolock the sash against movement On the other hand, when the improveddevices are applied to thie inner opposing sides of the inner part ofthe frame or window casing, the pressure of the device on the sideportions of `the sash will bepeXerted in an outward direction, either tolock the sash against upward and downward movement, or, when the sash isclosed, to sealv the same, as above specified. n The curved surfaces oropposed cam `edges provided by the curved flanges 6 and 7 will,

"tinuing' outwardly to the Vouter surface of not mar the window sash orthe inner opposing sides of the window casing or frame, as

`the device need only exert a slight binding be made invarious sizes,but for all practical purposes a standardized size will be adopted Y andmanufactured and have such roportions asto renderthe devicepractical-,for the purpose for which it has been devised.

T e nn roved fastening device is secured in applie position through themedium of one screw 10, which is passedthrough anopening l1 in theintermediate portion of the body 5, thesaidscrew being of suchconstruction that it firmly holds the devicein association with thewindow sash or innerl side of the window `frame and at thefsame timepermits a re uisite:` pivotal or'swinging movement of the asteningdevice thereon.v

In themodified `Structure,shown by Fig. 7 the features. are `essentiallythe same'asYA those,:described in connectionrwith the pre`` vferredform,- the diierencebeing in this instance'that one extremity 5*? of thebody 5 ,serves as a weight gravitating A feature,v owing `to theeccentricity of thev openin 12V corresponding to the opening l1 in theform` shown by Fig. 6. Furthermore, theonesde edge 13 extends in astraight'line almost fully from the flan e 6 to the iange 7, there beinga short angular straightedge 14' conthe flange 7. The opposite" sideedge of this modified formis more nearly like the struc`` ture shown by7 Vand comprises a straight edge 15 parallel with the edge 13` v and anangular straight ed e 16, continuing from the edge 15 outwar ly to theouteif surface of the flange 6. f

l The operation of this modified structure is essentially the sare asthat heretofore described in connection with the referred form and bothforms embody Yt e essential features .of the invention, namely, the flatbody 5, pivotally mounted and having opposite side edges composed ofVstrai ht lines arranged at an angle to each Vot er and presenting twocurved cam flangesfor engaging the window sash or adjacent ortion of thewindow frame or correspon ing parts of other `movable and. supportingstrlctures with which the device may be use V What is claimed as new is:A reversible fastener for windows, con sisting of a fiat body formed ofone piece of material and having the Vopposite ends provided with curvedvflanges rojected solely from the outer` side of the ody `and struckfrom two different centers and whose outer sides present opposingeccentric cani portions at obtuse angles and which latter facesextending reversely over the center of edge portions terminate at theends of said 10 the body, and also having opposite straight flangesopposite the outer terminals of the parallel side edge guiding portionsextendsaid parallel side edge portions. ing part Way the length of thefastener and y InV testimony whereof I have hereunto set eachterminating at one end with reverse my hand.
